PIPE

To all whom it may concern:

Be it known that we, FREEMAN A. DUNN and FREDERICK G. Gnasnn, citizensof the United States, residing at Keokuk, in the county of Lee and Stateof Iowa, have invented certain new and useful Improvements in Pipes, ofwhich the following is a specification.

This invention contemplates certain new and useful improvements inpipes, and the object of the invention is an improved pipe section, bymeans of which the pipe may be quickly and conveniently separated intoits parts, and the latter may be nested, if desired, to permit the pipeto be carried from place to place in compact form, and which is designedparticularly for use with pipe elbows, and is arraiiged to render theelbow yapable of being readily adjusted to regulate the angle thereof. i

\Vith these and other objects in view, that will more fully appear asthe description proceeds, the invention consists in certainconstructions and arrangements of the parts that we shall hereinafterfully describe and claim.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and accompanyingdrawings, in which:-

Figure 1 is a perspective view of av pipe elbow. embodying ourinvention. Fig.2 is a. perspective view of one of our improved Fig. 3 isa longitudinal section through the joint of the ends, of the pipesection, on the line S--3 of Fig. t. Fig. 4 is atransverse section onthe line 4 t of Fig. 3.

Corresponding and like parts are referred to-in the followingdescription and indicated in all the: views of the drawings by the samereference characters.

Each of our improved pipe-sections comprises a split ring 1, one end ofwhich is slit to form a'plurality oftongues that are initially hooked bybeing bent upwardly and backwardly, as shown. The other end of the ringis formed with a plurality of raised portions 3 and with a slot 4extending through each of said raised portions and facing the firstnamed end of the ring, said "raised portions being in alinement with andbeing arranged to receive the respective hooked tongues 2, which areadapted to protrude through the respective slots 4 thereof, and aredesigned be bent forwardly Specification of Letters Patent.

Application filed February 24, 190B.

Patented Jan. '19, 1909.

Serial No. 417,569.

against the raised portions to lock the two ends of the ring securelytogether.

In order to secure two adjacent pipe seetions detachably together, oneof the pipe sections is formed at one edge with an annular head 5,arranged for engagement with the outstanding rim (3 formed at theadjacent edge of the other pipe section.

In the practical use of our improved pipe sections, the rinnned sectionis applied to the beaded section, after the ends of the latter have beenlocked togethe and is com pressed with its rimmed end extending withinthe beaded end of the other section, said rinnned section being then'released to permit it to expand and the rim 6 thereof to spring intoengagen'lent with the head 5. When in such expanded position, thetongues 2 of the rinnned section are adapted to .protrude through therespective slots "t, and are then bent forwardly to lock the two ends ofthe rimmed section together and to lock the rim thereof in engagementwith the bead.

Although our improved pipe sections are illustrated as applied to a pipeelbow, it is to be understood that they are not limited to such use.

From the above description in connection with the accompanying drawing,it will be apparent that we have provided a simple, du'able and.efficient construction of pipe which may be readily adjusted and thesections of .which may be conveniently separated to permit the pipe tobe easily cleaned.

Having thus described the invention, what -we claim is 2- A pipe sectionconsisting of a split ring formed at one end with a raised portion openat its end adjacent to the other end of the ring, said other end of thering being formed with a tongue doubled upon itself to constitute ahook, said hook being received in the raised portion and engaging aportion of said first named end, the end of said tongue being againdoubled upon' itself,

forming a hook facing'in a direction op posite to that of the Fn-stnamed hook and engaging said raised portion.

In testimony whereof we atlix our signatures in presence of twowitnesses.
